摘要 |
<p>The invention concerns a method which consists in selectively destroying nitrous oxide at high temperature on catalysts consisting of refractory oxide agglomerates (alumina or zirconium) having intergranular porosity impregnated with a zirconium salt. The method is useful for treating gases in workshops producing nitric acid. The invention is also useful, using specific initiators, for treating gases rich in N>2<O produced in nitric oxidation of organic compounds.</p> |
